[0002] With the rapid development of marine aquaculture, oysters, as an important economic shellfish, play a vital role in meeting human needs for high-quality protein and enjoy broad consumer demand in the global market. Oyster farming not only brings significant economic benefits to coastal areas but also occupies an important position in the efficient utilization of marine resources and sustainable ecological development. To ensure the quality of oyster products and process management, and to guide farmers in timely harvesting, a comprehensive and systematic monitoring and testing mechanism must be implemented throughout the farming process.

[0014] The periodic sampling and testing method for oyster farming includes the following steps: S1. Start the mobile motor and move the mobile frame above the oyster farming cage to be tested; S2. Start the second hydraulic cylinder. The second hydraulic cylinder drives the drive plate to move downward. The drive plate drives the push block to move downward synchronously. The push block is inserted into the slot. The second inclined plane and the third inclined plane abut against each other, so that the limit block moves away from the rotating roller and releases the limit block from the rotating roller. S3. Start the first hydraulic cylinder. The first hydraulic cylinder drives the moving plate to move downward, so that the active roller and the rotating roller mesh with each other. At the same time, the two moving rods move towards each other, thereby driving the two supporting cylinders to move towards the rotating roller. The two supporting cylinders are located below the rotating roller. The supporting cylinders and the active roller clamp the rotating roller, so that the active roller and the rotating roller are kept in a meshed state. Then start the drive motor. The drive motor drives the second bevel gear to rotate through the synchronous sleeve and the synchronous rod. The second bevel gear drives the active roller to rotate through the first bevel gear. The active roller drives the rotating roller to rotate, so that the take-up roller plate winds up the wire rope, thereby driving the breeding cage to be lifted upward stably. S4. The second hydraulic cylinder drives the rotating roller and the culture cage to move upward, while the water pump is started to use high-pressure nozzles to wash the algae and silt on the culture cage; the camera can perform appearance inspection on the oysters and analyze their health status; the weighing sensor can collect the weight data of the oysters.

[0015] The beneficial effects of this invention are as follows: The aquaculture cage is fixed with a steel wire rope, causing it to sink to the bottom of the aquaculture pond. A movable frame moves on the mounting frame to the position of the rotating roller. A drive component drives the rotating roller to rotate, which in turn drives the winding reel to rotate, thereby winding the steel wire rope and allowing the aquaculture cage to move stably upwards. A lifting component then moves the rotating roller and the aquaculture cage upwards, separating the cage from the mounting frame. First, a high-pressure nozzle is used to wash away algae and silt from the aquaculture cage. Then, a weighing sensor collects oyster weight data, improving data accuracy. Real-time data feedback optimizes aquaculture decisions, improving oyster quality and yield. A camera allows for visual inspection of the oysters, analyzing their health status and enabling early disease detection, further improving aquaculture efficiency. This achieves fully automated assembly line operation, significantly reducing manual labor intensity and operational risks, and improving inspection efficiency. Attached Figure Description

The synchronizing bar 531 slides vertically with the synchronizing sleeve 56 through the synchronizing groove 561.

[0026] Start the first hydraulic cylinder 42, which drives the moving plate 43 to move downward, so that the active roller 46 and the rotating roller 2 mesh with each other. Then start the drive motor 55, which drives the bevel gear 2 54 to rotate through the synchronous sleeve 56 and the synchronous rod 53. The bevel gear 2 54 drives the active roller 46 to rotate through the bevel gear 1 51. The active roller 46 drives the rotating roller 2 to rotate, so that the take-up roller plate winds up the wire rope 22, thereby driving the breeding cage 23 to be lifted upward stably.

[0027] Reference Figure 3 , Figure 4 and Figure 6 On both sides of the drive roller 46, there are supporting cylinders 6, which are parallel to the drive roller 46.

[0028] The first hydraulic cylinder 42 drives the moving plate 43 to move downward, and the moving plate 43 drives the moving rod 63 to move downward. At the same time, the two moving rods 63 move towards each other, thereby driving the two supporting cylinders 6 to move towards the rotating roller 2.

The push block 81 is inserted into the slot 17, and the second inclined surface 82 and the third inclined surface 1521 abut against each other, causing the limiting block 15 to move away from the rotating roller 2, thus releasing the limiting block 15 from the rotating roller 2.

The supporting cylinder 6 drives the rotating roller 2 to move upward, causing the rotating roller 2 to disengage from the relief groove 13. Then the second hydraulic cylinder 72 drives the drive plate 41 to move upward, thereby driving the rotating roller 2 and the breeding cage 23 to move upward, so that the breeding cage 23 is separated from the mounting frame 1, so as to collect the oysters.

[0032] The implementation principle of the wastewater tank 35 in this application embodiment is as follows: the culture cage 23 is fixed by the wire rope 22, so that the culture cage 23 is submerged at the bottom of the culture pond. The moving frame 3 moves on the mounting frame 1 to the position of the rotating roller 2. The driving component 4 drives the rotating roller 2 to rotate, and the rotating roller 2 drives the winding reel 21 to rotate, thereby winding the wire rope 22, so that the culture cage 23 moves upward stably.

The culture decision is optimized through real-time data feedback, which improves the quality and yield of oysters. The camera 361 can be used to inspect the appearance of the oysters and analyze their health status. Diseases can be detected early, further improving the efficiency of culture. The fully automated assembly line operation is realized, which greatly reduces the intensity of manual labor and operational risks and improves the detection efficiency.

The push block 81 is inserted into the slot 17. The second inclined surface 82 and the third inclined surface 1521 abut against each other, so that the limit block 15 moves away from the rotating roller 2, and the limit block 15 is released from the limit of the rotating roller 2. S3. Start the first hydraulic cylinder 42. The first hydraulic cylinder 42 drives the moving plate 43 to move downward, so that the active roller 46 and the rotating roller 2 mesh with each other. At the same time, the two moving rods 63 move towards each other, thereby driving the two supporting cylinders 6 to move towards the rotating roller 2. The two supporting cylinders 6 are located below the rotating roller 2. The supporting cylinders 6 and the active roller 46 clamp the rotating roller 2, so that the active roller 46 and the rotating roller 2 remain in a meshing state. Then start the drive motor 55. The drive motor 55 drives the second bevel gear 54 to rotate through the synchronous sleeve 56 and the synchronous rod 53. The second bevel gear 54 drives the active roller 46 to rotate through the first bevel gear 51. The active roller 46 drives the rotating roller 2 to rotate, so that the take-up roller plate winds up the wire rope 22, thereby driving the breeding cage 23 to be lifted upward stably. S4. The second hydraulic cylinder 72 drives the rotating roller 2 and the breeding cage 23 to move upward, and at the same time the water pump 353 is started, and the high-pressure nozzle 351 is used to wash the algae and silt on the breeding cage 23; the camera 361 can perform appearance inspection on the oysters and analyze their health status; the weighing sensor can collect the weight data of the oysters.
